BACKGROUND

With the rapid development of Internet technologies, users can perform all kinds of activities, such as handling official businesses, entertainment, shopping, and money management. Services that support the activities can be provided through networks and can involve multiple service providers. The user can register for services provided by the service providers. After registration, the user may need to provide an account and password each time a service is to be accessed, so that the server can authenticate the user and provide the corresponding service.

For security reasons, the user may try to avoid using a same account and a same password for the multiple service providers. When the user wants to register with additional service providers for additional services, the user may be burdened with memorizing new account and passwords for each new service provider.

DETAILED DESCRIPTION

The following detailed description describes techniques for authentication and registration of a user, and is presented to enable any person skilled in the art to make and use the disclosed subject matter in the context of one or more particular implementations. Various modifications, alterations, and permutations of the disclosed implementations can be made and will be readily apparent to those of ordinary skill in the art, and the general principles defined can be applied to other implementations and applications, without departing from scope of the disclosure. In some instances, details unnecessary to obtain an understanding of the described subject matter can be omitted so as to not obscure one or more described implementations with unnecessary detail and inasmuch as such details are within the skill of one of ordinary skill in the art. The present disclosure is not intended to be limited to the described or illustrated implementations, but to be accorded the widest scope consistent with the described principles and features.

Implementations in the present disclosure can include the use of a server authentication key and a device authentication key that are set on a server and a wearable device. Using these keys, the server can authenticate (through interaction with a terminal) a wearable device of a user. The authentication can occur without requiring the user to memorize or enter any account or password.

Wearable devices can include, for example, portable devices that can be worn by a user or integrated into a user's clothing or accessory. Example wearable devices include wristbands, smart watches, smart shoes, smart clothes, smart glasses, smart helmets, smart rings, and other devices that can provide some computing functionality. Wearable devices can be connected to a terminal, such as a smart phone, a tablet computer, or a personal computer, through a hardware interface or a wireless local area network. When connected, wearable devices can implement a variety of functions by exchanging data with the terminal.

Each wearable device can generally be specific to one user, since the user may tend to wear their wearable device whenever and wherever possible. Implementations of the present application include techniques for authenticating a user. Authentication can occur by using storage and computing functions of the wearable device, without requiring the user to memorize and frequently input an account and a password.

FIG. 1 is a block diagram illustrating an example of a network environment 100, according to an implementation of the present disclosure. The network environment 100 includes a wearable device 102 that is connected to a terminal 104. The connection can be made, for example, through a hardware interface or a wireless local area network. The hardware interface can be, for example, an audio interface, a Universal Serial Bus (USB) interface, or some other interface. The wireless local area network can be BLUETOOTH, wireless-fidelity (Wi-Fi), ZIGBEE, or some other network. The terminal 104 can be, for example, a smart phone, a tablet computer, or a personal computer.

The terminal 104 can communicate with a server 106 through a communication network 108 such as the Internet, a mobile communication network, or combination of networks. In one example scenario, a user using the wearable device 102 connected to the terminal 104 can send an access request to the server 106, such as to authenticate the user. In implementations of the present disclosure, no limitations are made as to the type of the terminal 104, hardware interfaces and a wireless local area network protocols through which the wearable device 102 is connected to the terminal 104, protocols and network structures of the communication network 108, and specific implementations of the server 106.

FIG. 2 is a flowchart illustrating an example of a method 200 for server-side authentication of a user, according to an implementation of the present disclosure. For example, method 200 can be used for authenticating a user of the wearable device 102. Authentication can be completed using a combination of the terminal 104 and the server 106. For clarity of presentation, the description that follows generally describes method 200 in the context of the other figures in this description. However, it will be understood that method 200 can be performed, for example, by any suitable system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method 200 can be run in parallel, in combination, in loops, or in any order.

At 210, an authentication request is received from a terminal. For example, the authentication request can be sent by a user through a terminal. The authentication request can include at least one of a user identifier of a user and a wearable device identifier of the user. The server 106 can store a relationship between the user identifier, the wearable device identifier, and a server authentication key.

The authentication request can be received, for example, when the user requests a service from the server 106 that requires identity authentication of the user, such as during a login, prior to access to a personal account, during a payment, or for some other reason. The server 106 can then require, from the terminal, related information for authenticating the user. In response, the terminal can send an authentication request to the server. The authentication request can include one or both of the user identifier of the user and the wearable device identifier of the user. After the server receives the authentication request of the terminal, identification of the user requesting authentication can be made using one or both of the user identifier and the wearable device identifier.

In some implementations, the server 106 can store a corresponding relationship between a user identifier, a wearable device identifier, and a server authentication key. The user identifier is a unique identifier by which the server can distinguish the user from other users. The user identifier can include, for example, a user name, a registered email address, or some other user identifying information. If the user is bound to a mobile terminal, the user identifier can also be a number, such as an International Mobile Equipment identity (IMIE) number. The wearable device identifier can be used to uniquely represent the wearable device. The wearable device identifier can vary depending on each different device type and each different wireless local area network protocol that is used. The wearable device identifier can generally be a hardware address of the wearable device, such as a Media Access Control (MAC) address. The server authentication key can be stored on the server 106. The server authentication key can be the same as (or can correspond to) a device authentication key, which can be stored on the wearable device according to an encryption algorithm using the server authentication key. The wearable device identifier and the server authentication key stored on the server can have a one-to-one correspondence with each other. If a particular user has more than one wearable device that can require authentication, a same user identifier can correspond to two or more wearable device identifiers and server authentication keys. A relationship between the user identifier, the wearable device identifier, and the server authentication key can be stored in the server 106 locally. In some implementations, the relationship can also be stored in other storage devices accessible to the server 106, such as in a disk array for storing local area networks or in a cloud storage network.

In some implementations, the authentication request is a payment request sent by a user through a payment client terminal. In some implementations, the payment request is triggered by information which is selected by the user on the payment client terminal and can indicate making a payment by a wearable device. A payment operation is performed after the authentication is successful.

In some implementations, the authorization request is a payment request sent to a server in response to a payment operation of a user on a payment client terminal. The payment request includes a user identifier and/or a wearable device identifier of the user. In some implementations, the payment operation of the user on the payment client terminal is specifically an operation which is selected by the user and indicates making a payment by a wearable device. A payment operation is performed after the authentication is successful.

In some implementations, a payment authentication information sent by a payment client terminal is received at a server. The payment authentication information includes downlink authentication information issued by the server based on a payment request of a user sent by the payment client terminal. Uplink authentication information is generated that is based on a stored device authentication key and the downlink authentication information. The uplink authentication information is sent to the payment client terminal. The payment client terminal sends the uplink authentication information to the server. The server can authenticate the user based on the uplink authentication information and perform a payment operation after the authentication is successful. From 210, method 200 proceeds to 220.

At 220, downlink authentication information is acquired by the server. For example, the server 106 can issue a detection instruction to the terminal that includes the downlink authentication information and the wearable device identifier. The downlink authentication information can be a part of (and included in) the authentication data. In some implementations, the downlink authentication information can also be a ciphertext after the authentication data is encrypted using the server authentication key stored on the server 106. The server 106 can obtain the authentication data in any manner. For example, the server can randomly generate the authentication data, or the server 106 can capture a certain number of bytes from a file or an image. The server 106 can generate the authentication data locally on its own. In some implementations, the server 106 can also acquire the authentication data from another server. From 220, method 200 proceeds to 230.

After receiving the authentication request of the terminal, the server 106 can extract one or both of the user identifier and the wearable device identifier in the authentication request. The server 106 can determine whether one or both of the user identifier and the wearable device identifier are included. The determination can be made using the stored relationship between the user identifier, the wearable device identifier, and the server authentication key. The server can reject the authentication request if neither one of the user identifier nor the wearable device identifier is included, or if the user identifier and the wearable device identifier in the authentication request do not belong to a same user. Otherwise, the server can acquire authentication data. For downlink authentication information that is in plain text format, the server can encapsulate the authentication data and the wearable device identifier of the user in a detection instruction, and the server can issue the detection instruction to the terminal. For downlink authentication information that is in ciphertext format, the server can encrypt the authentication data by using a server authentication key corresponding to the user identifier or the wearable device identifier in the authentication request. The server can also generate downlink authentication information, encapsulate the downlink authentication information and the wearable device identifier of the user in a detection instruction, and issue the detection instruction to the terminal.

At 230, a detection acknowledgment is received by the server. For example, the detection acknowledgment can be returned by the terminal and can include uplink authentication information that is generated by a wearable device designated in the detection instruction according to a device authentication key and the downlink authentication information. The device authentication key can be the same as (or can correspond to) the server authentication key.

The server 106 can receive the detection acknowledgment returned by the terminal, extract the uplink authentication information therefrom, and determine whether the uplink authentication information is matched with the downlink authentication information. The matching can be done using the server authentication key of the user to determine an authentication result of the user. When the uplink authentication information is in plain text format, the uplink authentication information can be compared with authentication data for generating a ciphertext, or the uplink authentication information that has been encrypted by using the server authentication key can be compared with the downlink authentication information. If a match is found, then the user can pass the authentication; otherwise, the authentication can fail. When the uplink authentication information is in ciphertext format, the uplink authentication information can be decrypted using the server authentication key, and then compared with the downlink authentication information. If there is a match, then the user passes the authentication; otherwise, the authentication can fail. From 230, method 200 proceeds to 240.

At 240, the user is authenticated by the server. Authentication can include, for example, matching the downlink authentication information with the uplink authentication information by using the server authentication key of the user. If the matching succeeds, then the user passes the authentication. The server can return an authentication result to the terminal that indicates whether the user passes the authentication. After 240, method 200 stops.

FIG. 3 is a flowchart illustrating an example of a method 300 for terminal-side authentication of a user, according to an implementation of the present disclosure. Method 300 is the terminal-side counterpart of the server-side method 200 of FIG. 2. Method 300 can be used, for example, to authenticate a user of the wearable device 102. Authentication can be completed using a combination of the terminal 104 and the server 106. For clarity of presentation, the description that follows generally describes method 300 in the context of the other figures in this description. However, it will be understood that method 300 can be performed, for example, by any suitable system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method 300 can be run in parallel, in combination, in loops, or in any order.

At 310, an authentication request is sent by a terminal connected to a wearable device of a user. For example, the authentication request can be sent to the server 106 subsequent to an operation of the user. The authentication request can include at least one of a user identifier and a wearable device identifier of the user. From 310, method 300 proceeds to 320.

At 320, a detection instruction of the server is received at the terminal. The detection instruction can include downlink authentication information and the wearable device identifier. From 320, method 300 proceeds to 330.

At 330, the downlink authentication information is sent by the terminal to a wearable device designated in the detection instruction. For example, the terminal 104 can receive uplink authentication information returned by the wearable device. The uplink authentication information can be generated by the wearable device according to a stored device authentication key and the downlink authentication information. The device authentication key can be the same as (or can correspond to) a server authentication key stored in the server. In some implementations, if the wearable device designated in the detection instruction has not yet been connected to the terminal, the terminal can be required to first complete a connection with the wearable device according to a wireless local area network protocol supported by the wearable device.

After receiving the downlink authentication information, if the downlink authentication information is in plain text format, then the wearable device can encrypt the downlink authentication information by using the device authentication key to generate uplink authentication information as a ciphertext. If the downlink authentication information is in a ciphertext format, then the wearable device can decrypt the downlink authentication information by using the device authentication key to generate uplink authentication information in a plain text format. As a result, the downlink authentication information in a plain text format can correspond to the uplink authentication information in a ciphertext format. Similarly, the downlink authentication information in a ciphertext format can correspond to the uplink authentication information in a plain text format. The wearable device can then return the uplink authentication information to the terminal.

After receiving the uplink authentication information returned by the wearable device, the terminal can encapsulate the uplink authentication information in a detection acknowledgment that can be sent to the server. The detection acknowledgment can include the wearable device identifier. From 330, method 300 proceeds to 340.

At 340, a detection acknowledgment is sent to the server that includes the uplink authentication information. For example, the detection acknowledgment can be sent to the server 106. From 340, method 300 proceeds to 350.

At 350, the user is authenticated. Authentication can include, for example, receiving a user authentication result determined by the server according to the uplink authentication information, the downlink authentication information, and the server authentication key.

In some implementations, a server authentication key and a device authentication key (which can be the same) can be set on a server and a wearable device. The server can authenticate, through interaction with the terminal, a designated wearable device by using the device authentication key stored on the wearable device and the server authentication key stored on the server. This results in authentication of the user corresponding to the wearable device. In this process, the user neither needs to memorize, use, or input any account or password information during authentication, which can reduce the burden on the user and improve the efficiency of the user when acquiring a network service.

In some implementations, a user public key of the user can be stored on the server. Also, a user private key of the user can be stored on the terminal. In some implementations, user identification can use a different user public key and a different user private key, which can serve as a pair of keys in asymmetric encryption. The user public key stored on the server can correspond to the user identifier, the wearable device identifier, and the server authentication key of the user. In these and other implementations, the terminal can sign (or annotate) data that is included in the detection acknowledgment by using the stored user private key. The detection acknowledgment can include the uplink authentication information and can also include the wearable device identifier, the user identifier, and other data. The terminal can send the signed detection acknowledgment to the server. The server can perform signature verification on the detection acknowledgment by using the user public key of the user. If the detection acknowledgment passes the verification, step 240 can be performed to match the uplink authentication information with the downlink authentication information. If the detection acknowledgment fails to pass the signature verification, then the terminal is notified that the authentication has failed. Some implementations can mandate that a terminal to which a wearable device is connected is required store a user private key of a user when the user uses the wearable device for authentication, which can achieve better security.

In some implementations, a terminal identifier can be added to the corresponding relationship between the user identifier, the wearable device identifier, and the server authentication key of the user stored on the server. Addition of the terminal identifier can allow the terminal to be used when performing user authentication through the wearable device connected to the terminal. In such a situation, the server can store a corresponding relationship between the user identifier, the wearable device identifier, and the server authentication key of the user and the terminal identifier. An authentication request sent by the terminal to the server can include a terminal identifier of the terminal. After receiving the authentication request, the server can identify, in the stored corresponding relationship, a terminal identifier corresponding to the user identifier or the wearable device identifier in the authentication request. The server can then compare the terminal identifier with the terminal identifier for sending the authentication request. If the identifiers are the same, then step 220 can be performed to continue the authentication process. If the identifiers are different, then the authentication request of the terminal can be rejected, thus failing the user authentication. Such an implementation is equivalent to binding a wearable device to a terminal capable of performing user authentication through the wearable device. As a terminal (especially a mobile terminal) generally is also specific to a user, binding a wearable device to the terminal can significantly improve the security of user authentication.

The authentication process can be applied to any scenario that requires authenticating a user identity. Such scenarios can include, for example, user identity authentication in the case of login, identity authentication when a user accesses a personal account, identity authentication when a user makes a payment through a third-party payment platform, and in other scenarios. In these and other scenarios, after the user passes the authentication, the server can provide a subsequent service, and the terminal can execute a subsequent operation. For example, in payment scenarios requiring identity authentication, the authentication request sent by the terminal to a payment server can be a payment request. After the user passes the authentication, the payment server can provide a payment service for the user passing the authentication. After receiving, from the server, an authentication result indicating that the user has passed the authentication, the terminal can interact with the payment server to complete a payment operation of the user.

In some implementations, the relationship between the user identifier, the wearable device identifier, and the server authentication key of the user can be preset on the server. Further, corresponding device authentication key can be preset on the wearable device. In some implementations, the relationship can first be generated on the server, and the device authentication key can be provided to and stored on the wearable device through a registration process before the authentication process. After 350, method 300 stops.

FIG. 4 is a flowchart illustrating an example of a method 400 for server-side registration of a wearable device, according to an implementation of the present disclosure. For example, method 400 can be used for registering a user of the wearable device 102. Registration can be completed using a combination of the terminal 104 and the server 106. For clarity of presentation, the description that follows generally describes method 400 in the context of the other figures in this description. However, it will be understood that method 400 can be performed, for example, by any suitable system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method 400 can be run in parallel, in combination, in loops, or in any order.

At 410, a wearable device registration request that is sent through a terminal is received at a server. The registration request can include a user identifier and a wearable device identifier of a user. The registration request can be sent, for example, when the user registers a wearable device with the server on the terminal, and the terminal sends a wearable device registration request to the server according to an operation of the user. From 410, method 400 proceeds to 420.

At 420, a server authentication key of the user and a device authentication key are acquired, and a write instruction is issued to the terminal that includes the device authentication key and the wearable device identifier of the user.

After receiving the wearable device registration request of the terminal, the server can acquire a server authentication key and a device authentication key that are used for the encryption algorithm and that correspond to the wearable device identifier. Acquisition can be according to an encryption algorithm adopted for the uplink authentication information or downlink authentication information in the authentication process. The server authentication key and the device authentication key can be one key, such as a key used in a symmetric encryption algorithm. The server authentication key and the device authentication key can also be a pair of keys, such as a public key and a private key used in an asymmetric encryption algorithm. The server can generate the server authentication key and the device authentication key by itself, or the server can obtain the server authentication key and the device authentication key from another server. The server can encapsulate the acquired device authentication key and the corresponding wearable device identifier in a write instruction that the server can send to the terminal. From 420, method 400 proceeds to 430.

At 430, the wearable device is registered. Registration can include receiving a write acknowledgment returned by the terminal. If the write acknowledgment indicates that the device authentication key has been successfully stored in a wearable device designated in the write instruction, then the server can store a corresponding relationship between the user identifier, the wearable device identifier, and the server authentication key of the user. After 430, method 400 stops.

FIG. 5 is a flowchart illustrating an example of a method 500 for terminal-side registration of a wearable device, according to an implementation of the present disclosure. Method 500 is the terminal-side counterpart of the server-side method 400 of FIG. 4. Method 500 can be used for registering a user of the wearable device 102. Registration can be completed using a combination of the terminal 104 and the server 106. For clarity of presentation, the description that follows generally describes method 500 in the context of the other figures in this description. However, it will be understood that method 500 can be performed, for example, by any suitable system, environment, software, and hardware, or a combination of systems, environments, software, and hardware, as appropriate. In some implementations, various steps of method 500 can be run in parallel, in combination, in loops, or in any order.

At 510, a wearable device registration request is sent by a terminal to a server. The registration request can include a user identifier and a wearable device identifier of the user. From 510, method 500 proceeds to 520.

At 520, a write instruction of the server is received at the terminal. The write instruction can include a device authentication key and the wearable device identifier of the user. From 520, method 500 proceeds to 530.

At 530, the device authentication key is written to the wearable device designated in the write instruction. For example, after the terminal receives the write instruction from the server, the terminal can send the device authentication key in the write instruction to a wearable device. The write instruction can include a request that the wearable device store the device authentication key. In some implementations, such as during the use of permission settings on the wearable device, the wearable device can complete storage of the device authentication key only after the user confirms the write operation. In some implementations, confirmation can occur when the user taps on the wristband when prompted for confirmation. From 530, method 500 proceeds to 540.

At 540, registering the wearable device, including sending a write acknowledgment to the server, the write acknowledgment including a message indicating whether the device authentication key is successfully written. For example, after completing the write operation with the wearable device, the terminal can encapsulate a message in a write acknowledgment that indicates whether the device authentication key was successfully written. After 540, method 500 stops.

In some implementations, the server can require the terminal to provide a password of the user to improve security of registration of the wearable device. For example, the server can receive the write acknowledgment of the terminal, and if the message carried in the write acknowledgment is that the device authentication key has been successfully stored in the wearable device, the server can issue a password confirmation request to the terminal. The confirmation request can require the terminal to provide a password of the user corresponding to the wearable device. The terminal can receive the password confirmation request of the server, and the terminal can return a password confirmation acknowledgment that includes the user password input by the user. After receiving the password confirmation acknowledgment that includes the user password, if the server determines that the user password is correct, then the server can store the corresponding relationship between the user identifier, the wearable device identifier, and the server authentication key of the user. Registration of the wearable device can then be indicated as being successful. If the user password is incorrect, then the registration request of the terminal can be rejected, and registration can fail. The server can send a registration result to the terminal that indicates success or failure.

In some implementations, a user public key and a user private key of the user can be generated automatically in the registration process. Specifically, after a successful operation of writing the device authentication key in the wearable device by the terminal, the terminal can generate a user public key and a user private key of the user according to an algorithm. The terminal can then store the generated user private key locally, encapsulate the user public key in a write acknowledgment, and send the write acknowledgment to the server. After the terminal successfully writes the device authentication key in the wearable device or it is verified that the user password is correct, the server can store a corresponding relationship between the user identifier, the wearable device identifier, the server authentication key, and the user public key of the user.

In some implementations, a server public key and a server private key can be preset on the server, and a terminal private key and a terminal public key can be preset on the terminal. For example, the server public key and the terminal private key can be a pair of keys, and the server private key and the terminal public key can be a pair of keys. In these and other implementations, the server can sign the detection instruction by using the stored server private key, and the server can send the signed detection instruction to the terminal. The terminal can perform signature verification on the received detection instruction by using the stored terminal public key. The terminal can reject the detection instruction if the verification fails, in which case registration fails. In some implementations, the server can sign the write instruction by using the stored server private key, and the server can send the signed write instruction to the terminal. The terminal can perform signature verification on the received write instruction by using the stored terminal public key. The terminal can reject the write instruction if the verification fails, in which case registration fails. The terminal can sign the write acknowledgment by using the stored terminal private key, and the terminal can send the signed write acknowledgment to the server. The server can perform signature verification on the received write acknowledgment by using the stored server public key, and the server can reject the registration request of the terminal, in which case verification fails.

In some implementations, the server and the terminal can conduct communication through an encrypted channel, such as to further improve security of wearable device registration and user authentication. For example, the detection instruction and the detection acknowledgment in the authentication method embodiment and the write instruction and the write acknowledgment in the registration method embodiment all can be transmitted in an encrypted channel.

In some implementations, a payment client terminal running on the terminal can authenticate a user identity in a payment process by using a wearable device connected to the terminal. A specific process of this embodiment is as follows:

On the wearable device, a payment binding request of the payment client terminal is received. The payment binding request can include a device authentication key of the wearable device. In response to the payment binding request issued by the user through the payment client terminal, the wearable device can store the device authentication key included in the payment binding request in a local memory.

When making a payment operation on the payment client terminal, the user can select the wearable device to make a payment, which can trigger a response of the payment client terminal and send a payment request to the server. The payment request can include a user identifier and/or a wearable device identifier of the user.

After receiving the payment request sent by the user through the payment client terminal, the server can acquire downlink authentication information. The server can also issue, to the payment client terminal, an authentication instruction that includes the downlink authentication information and the wearable device identifier.

The payment client terminal can receive the authentication instruction issued by the server. The payment client terminal can include the downlink authentication information in payment authentication information and send the payment authentication information to a wearable device designated in the authentication instruction.

The wearable device can receive the payment authentication information sent by the payment client terminal. The wearable device can extract, from the payment authentication information, the downlink authentication information issued by the server based on the payment request of the user sent by the payment client terminal. The wearable device can generate uplink authentication information according to the stored device authentication key and the downlink authentication information. The wearable device can send the uplink authentication information to the payment client terminal. The payment client terminal can receive the uplink authentication information returned by the wearable device and can include the uplink authentication information in authentication response information and sends the authentication response information to the server.

The server can receive the authentication response information that includes the uplink authentication information returned by the payment client terminal. The server can match the downlink authentication information with the uplink authentication information by using the server authentication key of the user. The user can pass the authentication if the matching succeeds, and the user can perform a payment operation after the authentication is successful. The server authentication key of the user can be the same as the device authentication key of the wearable device designated in the authentication instruction.

In some implementations, a server authentication key and a device authentication key (which can be identical) can be set on a server and a wearable device. The wearable device can be authenticated by using the device authentication key and the server authentication key. In this way, payment authentication can be completed for a user corresponding to the wearable device, and the user can make a payment on a payment client terminal by using the wearable device. In this process, the user neither needs to memorize, use, or input any account or password information during authentication, which can reduce the burden on the user and improve the efficiency of the user when acquiring a network service.

In some implementations, after registering a wristband with a payment server through a client terminal, such as through an application running on a mobile phone terminal, the user can complete a network payment through the wristband without inputting any account and any password. A server public key and a terminal private key in a pair (as well as a server private key and a terminal public key in a pair) can be preset on the payment server and the client terminal. The payment server can be a server that runs a server terminal program corresponding to the client terminal. The payment server can also be a server of a third-party payment platform that supports the client terminal. An example process is as follows.

A user can send a wearable device registration request to a payment server through a client terminal, such as using an application (or app) running on a mobile phone terminal to apply for opening of wristband payment. The client terminal can upload a user identifier (such as an account of the user on the payment server), a mobile phone terminal identifier (such as an IMEI), and a wristband identifier (such as a wristband MAC address) in the registration request to the server.

The payment server can generate, through a predetermined algorithm, a symmetric key for authenticating a wristband, such as using a server authentication key and a device authentication key that are the same. The payment server can sign the symmetric key, the user identifier, and the wristband identification together through a preset server private key. The payment server can then encapsulate the signed symmetric key, user identifier, and wristband identifier in a write instruction, and the payment server can send the write instruction to the client terminal through an encrypted channel between the payment server and the client terminal.

After receiving the write instruction of the server terminal, the client terminal can verify validity of the data in the write instruction according to a preset terminal public key, and the client terminal can directly reject the write instruction if the data is invalid. If the validity verification succeeds, the client terminal can be connected to a wristband designated in the write instruction. After the connection is successful, the client terminal can write the symmetric key issued by the payment server in the wristband. In some implementations, confirmation can occur when the user taps on the wristband when prompted for confirmation, after which the symmetric key can be written in a storage area of the wristband.

After the write operation is successful, the client terminal can generate a pair of asymmetric keys according to the user identifier, such as a user public key and a user private key corresponding to the user identifier. The client terminal can sign a result indicating whether the write operation is successful. The result can include the wristband identifier and the user public key generated through a preset terminal private key. The client terminal can encapsulate the signed information in a write acknowledgment and send the write acknowledgment to the payment server through an encrypted channel. The user private key can be stored locally by the client terminal.

After receiving the write acknowledgment of the client terminal, the payment server can verify the signature of the client terminal through a preset server public key. The payment server can reject the registration request of the client terminal if the verification fails. After the signature verification succeeds, the payment server can issue a password confirmation request to the client terminal, such as to require the client terminal to provide a password of an account of the user on the payment server.

The client terminal can display, to the user, prompt information for inputting a password. The user can input the password of his/her account on the payment server. The client terminal can send a password confirmation acknowledgment that includes the received password to the payment server.

The payment server can verify the user password in the password confirmation acknowledgment. After the verification succeeds, the payment server can store a corresponding relationship between the symmetric key (such as the server authentication key), the user identifier, the mobile phone identifier, the wristband identifier, and the user public key generated by the client terminal. The payment server can then notify the client terminal that the wristband is registered successfully, at which time the registration process can end.

After the wristband is registered successfully on the payment server, if the user is hoping to make a payment through the wristband, the user can send a payment authentication request to the server through the client terminal. The authentication request can include information of an order to be paid, a user identifier, a mobile phone terminal identifier, and a wristband identifier.

After receiving the authentication request of the client terminal, the payment server can compare the mobile phone terminal identifier in the authentication request with the mobile phone terminal identifier in the stored corresponding relationship, which corresponds to the wristband identifier in the authentication request. If the identifiers are different, the authentication request can be rejected, and the payment can fail. If the identifiers are the same, the payment server can generate random plaintext data that is then used as downlink authentication information. The payment server can sign the downlink authentication information, the user identifier, and the wristband identifier by using a preset server private key. The payment server can then encapsulate the information in a detection instruction and send the detection instruction to the client terminal through an encrypted channel between the payment server and the client terminal.

After receiving the detection instruction of the payment server, the client terminal can first verify validity of signature data in the detection instruction according to a preset terminal public key. If the data is invalid, the detection instruction can be rejected, and the payment can fail. After validity verification of the signature is successful, the client terminal can connected to a wristband designated in the detection instruction. After the connection is successful, the client terminal can send the downlink authentication information in the detection instruction to the wristband. The wristband can encrypt the downlink authentication information by using the stored symmetric key to generate uplink authentication information, and the wristband can return the uplink authentication information to the client terminal. The process of encrypting the downlink authentication information by the wristband does not require user confirmation, which can further simplify user operations and improve the user's experiences.

After receiving the uplink authentication information generated by the wristband, the client terminal can sign the uplink authentication information using a locally-stored user private key. The client terminal can then encapsulate the signed data and the signed wristband identifier in a detection acknowledgment and sends the detection acknowledgment to the payment server through an encrypted channel between the client terminal and the payment server.

After receiving the detection acknowledgment uploaded by the client terminal, the payment server can perform signature verification on the detection acknowledgment according to the user public key corresponding to the wristband identifier in the detection acknowledgment. If the signature verification fails, the authentication request can fail. After the signature verification succeeds, the payment server can encrypt the downlink authentication information by using a symmetric key corresponding to the wristband identifier. The payment server can then compare the encrypted data with the uplink authentication information in the detection acknowledgment. Comparison can determine, for example, whether the downlink authentication information encrypted by the payment server is the same as the downlink authentication information encrypted by the wristband. If the information matches, then the payment server can return a message of successful authentication to the client terminal and continues paying an order. If the information does not match, then the payment server can return a message of unsuccessful authentication to the client terminal. After receiving the message of successful authentication, the client terminal can complete a user order payment operation together with the payment server. If receiving the message of unsuccessful authentication, then the client terminal can notify the user that this payment cannot be completed due to unsuccessful authentication.

Implementations of the subject matter and the functional operations described in this specification can be implemented in digital electronic circuitry, in tangibly embodied computer software or firmware, in computer hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them. Software implementations of the described subject matter can be implemented as one or more computer programs, that is, one or more modules of computer program instructions encoded on a tangible, non-transitory, computer-readable computer-storage medium for execution by, or to control the operation of, data processing apparatus. Alternatively, or additionally, the program instructions can be encoded in/on an artificially generated propagated signal, for example, a machine-generated electrical, optical, or electromagnetic signal that is generated to encode information for transmission to suitable receiver apparatus for execution by a data processing apparatus. The computer-storage medium can be a machine-readable storage device, a machine-readable storage substrate, a random or serial access memory device, or a combination of computer-storage mediums. Configuring one or more computers means that the one or more computers have installed hardware, firmware, or software (or combinations of hardware, firmware, and software) so that when the software is executed by the one or more computers, particular computing operations are performed.

The term “real-time,” “real time,” “realtime,” “real (fast) time (RFT),” “near(ly) real-time (NRT),” “quasi real-time,” or similar terms (as understood by one of ordinary skill in the art), means that an action and a response are temporally proximate such that an individual perceives the action and the response occurring substantially simultaneously. For example, the time difference for a response to display (or for an initiation of a display) of data following the individual's action to access the data can be less than 1 ms, less than 1 sec., or less than 5 secs. While the requested data need not be displayed (or initiated for display) instantaneously, it is displayed (or initiated for display) without any intentional delay, taking into account processing limitations of a described computing system and time required to, for example, gather, accurately measure, analyze, process, store, or transmit the data.

The terms “data processing apparatus,” “computer,” or “electronic computer device” (or equivalent as understood by one of ordinary skill in the art) refer to data processing hardware and encompass all kinds of apparatus, devices, and machines for processing data, including by way of example, a programmable processor, a computer, or multiple processors or computers. The apparatus can also be, or further include special purpose logic circuitry, for example, a central processing unit (CPU), an FPGA (field programmable gate array), or an ASIC (application-specific integrated circuit). In some implementations, the data processing apparatus or special purpose logic circuitry (or a combination of the data processing apparatus or special purpose logic circuitry) can be hardware- or software-based (or a combination of both hardware- and software-based). The apparatus can optionally include code that creates an execution environment for computer programs, for example, code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of execution environments. The present disclosure contemplates the use of data processing apparatuses with or without conventional operating systems, for example LINUX, UNIX, WINDOWS, MAC OS, ANDROID, IOS, or any other suitable conventional operating system.

A computer program, which can also be referred to or described as a program, software, a software application, a module, a software module, a script, or code can be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data, for example, one or more scripts stored in a markup language document, in a single file dedicated to the program in question, or in multiple coordinated files, for example, files that store one or more modules, sub-programs, or portions of code. A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

While portions of the programs illustrated in the various figures are shown as individual modules that implement the various features and functionality through various objects, methods, or other processes, the programs can instead include a number of sub-modules, third-party services, components, libraries, and such, as appropriate. Conversely, the features and functionality of various components can be combined into single components, as appropriate. Thresholds used to make computational determinations can be statically, dynamically, or both statically and dynamically determined.

The methods, processes, or logic flows described in this specification can be performed by one or more programmable computers executing one or more computer programs to perform functions by operating on input data and generating output. The methods, processes, or logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, for example, a CPU, an FPGA, or an ASIC.

Computers suitable for the execution of a computer program can be based on general or special purpose microprocessors, both, or any other kind of CPU. Generally, a CPU will receive instructions and data from and write to a memory. The essential elements of a computer are a CPU, for performing or executing instructions, and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to, receive data from or transfer data to, or both, one or more mass storage devices for storing data, for example, magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, for example, a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a global positioning system (GPS) receiver, or a portable storage device, for example, a universal serial bus (USB) flash drive, to name just a few.

The memory can store various objects or data, including caches, classes, frameworks, applications, modules, backup data, jobs, web pages, web page templates, data structures, database tables, repositories storing dynamic information, and any other appropriate information including any parameters, variables, algorithms, instructions, rules, constraints, or references thereto. Additionally, the memory can include any other appropriate data, such as logs, policies, security or access data, reporting files, as well as others. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.

Input can also be provided to the computer using a touchscreen, such as a tablet computer surface with pressure sensitivity, a multi-touch screen using capacitive or electric sensing, or other type of touchscreen. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, for example, visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's client device in response to requests received from the web browser.

The term “graphical user interface,” or “GUI,” can be used in the singular or the plural to describe one or more graphical user interfaces and each of the displays of a particular graphical user interface. Therefore, a GUI can represent any graphical user interface, including but not limited to, a web browser, a touch screen, or a command line interface (CLI) that processes information and efficiently presents the information results to the user. In general, a GUI can include a plurality of user interface (UI) elements, some or all associated with a web browser, such as interactive fields, pull-down lists, and buttons. These and other UI elements can be related to or represent the functions of the web browser.

The components of the system can be interconnected by any form or medium of wireline or wireless digital data communication (or a combination of data communication), for example, a communication network. Examples of communication networks include a local area network (LAN), a radio access network (RAN), a metropolitan area network (MAN), a wide area network (WAN), Worldwide Interoperability for Microwave Access (WIMAX), a wireless local area network (WLAN) using, for example, 802.11 a/b/g/n or 802.20 (or a combination of 802.11x and 802.20 or other protocols consistent with this disclosure), all or a portion of the Internet, or any other communication system or systems at one or more locations (or a combination of communication networks). The network can communicate with, for example, Internet Protocol (IP) packets, Frame Relay frames, Asynchronous Transfer Mode (ATM) cells, voice, video, data, or other suitable information (or a combination of communication types) between network addresses.

The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.

While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any invention or on the scope of what can be claimed, but rather as descriptions of features that can be specific to particular implementations of particular inventions. Certain features that are described in this specification in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any suitable sub-combination. Moreover, although previously described features can be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination can be directed to a sub-combination or variation of a sub-combination.

Particular implementations of the subject matter have been described. Other implementations, alterations, and permutations of the described implementations are within the scope of the following claims as will be apparent to those skilled in the art. While operations are depicted in the drawings or claims in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed (some operations can be considered optional), to achieve desirable results. In certain circumstances, multitasking or parallel processing (or a combination of multitasking and parallel processing) can be advantageous and performed as deemed appropriate.

Moreover, the separation or integration of various system modules and components in the previously described implementations should not be understood as requiring such separation or integration in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
